Is polyurethane toxic?
Some of the liquid raw materials that go into making polyurethane are indeed toxic, and must be handled with caution. However, once the urethane reaction is completed, the solid material is safe to use as intended. NEVER burn polyurethane (the fumes are toxic), and the dust created when urethane is sanded can be toxic.
